Worked practice questions

The sum of all the alleles in a population is called the:

  1. Gene pool
  2. Genome map
  3. Gene locus
  4. Genotype
Show answer and solution

Correct answer: A. Gene pool

1. Population genetics needs a term for all the genetic variation present. 2. The gene pool is the sum of all the alleles in a population. 3. It is the pool that evolutionary forces act on. 4. A genome or a locus describes one individual or one site, not the population. _Source: OpenStax Biology 2e (CC BY 4.0), Ch 19 'The Evolution of Populations', sections 19.1-19.3_

Population change over time is given which name in the modern synthesis?

  1. Devolution
  2. Microevolution
  3. Macroevolution
  4. Coevolution
Show answer and solution

Correct answer: B. Microevolution

1. The modern synthesis names change at two different scales. 2. The theory connects population change over time, which is microevolution. 3. Macroevolution is the other scale named in the same sentence. 4. It covers the processes giving rise to new species and higher taxonomic groups. _Source: OpenStax Biology 2e (CC BY 4.0), Ch 19 'The Evolution of Populations', sections 19.1-19.3_

Which pair of scientists stated the principle of equilibrium for a population's genetic makeup?

  1. Hardy and Weinberg
  2. Watson and Crick
  3. Darwin and Wallace
  4. Mendel and Morgan
Show answer and solution

Correct answer: A. Hardy and Weinberg

1. The equilibrium principle carries the names of its two authors. 2. English mathematician Godfrey Hardy and German physician Wilhelm Weinberg stated it. 3. They stated the principle of equilibrium in the early twentieth century. 4. It describes the population's genetic makeup. _Source: OpenStax Biology 2e (CC BY 4.0), Ch 19 'The Evolution of Populations', sections 19.1-19.3_
